Here a worker polishes the surface of an unfinished miniature submarine at a workshop of Zhang Wuyi, a farmer in China who is interested in scientific inventions. Wuyi has successfully tested his self-made miniature submarine "Shuguang Hao", which is 3.6 m (12 feet) long, 1.8 m (6 feet) high, has a maximum diving depth of 20 m (65 feet), can travel at a speed of 20 km per hour for 10 hours underwater and is dolphin shaped.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

Steph Mundell


The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

Simon Harriott


My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
